202 Mackenzie’s Voyages very briefly suggested, as promising the most important advantages to the trade of the united kingdoms.” 1 The fur-trader was not consciously an advocate of land settlement, but he was, nevertheless, a pioneer of settle- ment. Sir Alexander Mackenzie fought bitterly against the Selkirk colonisation scheme, and yet he did more than any other trader, or even Selkirk himself, to throw open the north-west to settlement. This transcontinental and trans-Pacific project was out- lined to Simcoe in 1794, who in his report to the Lords of Trade stated that Mackenzie had remarked on the necessity of combined action to secure the Pacific trade, and on the value of the Hudson Bay route. In January 1802, when in London, he laid proposals on the subject before Lord Hobart, the Colonial Secretary, suggesting the formation of a supreme civil and military establishment at Nootka, with a subordinate station on the Columbia River, and another in Sea Otter Harbour in latitude 55° north. His proposals were not acted on. In the retrospect it appears that Mackenzie’s foresight was prophetic. The North-West Company soon after initiated the policy of developing the fur-trade west of the Rockies. James Finlay was the first to follow Mackenzie over the mountains in 1797, exploring the river that bears his name. David ‘Thompson crossed the Rockies in the years 1801—2-3. In the first year he was commissioned to lead a party over to the Pacific slope to establish posts, but on reaching the headwaters of the Kootenay he was forced by a large party of Indians of the plains to retreat, as they feared that the Flat- heads west of the Rockies would be supplied with arms and ammunition. In 1805 Simon Fraser reached McLeod’s Lake, and 1 Mackenzie’s Voyages, Conclusion.
